BRADFORD MOGREGOR, OF COVINGTON, KENTUCKY.

AIR MEDICATOR AND lNJECTOR.

SPECIFICATION forming part of Letters Patent No. 297,427, dated April22, 1884.

Application filed February 23, 1884. (No model.)

To all whom it may concern:

Be it known that I, BRADFORD McGnncoR, a citizen of the United States,residing at Govington, in the county of Kenton and State of Kentucky,have invented certain new and useful Improvements in Devices forMedicating Air and Applying the Same; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled. in the art to which it appertains to make and usethe same, reference being had to the accompanying-drawings, and to theletters and figures of reference marked thereon, which form apart ofthis specification.

My invention relates to devices for medicating air and applying same tothe affected portion of the patients body. It consists in the novelconstruction, combination, and arrangement 0f the several parts, as willbe hereinafter more fully described and claimed.

In the drawings, Figure 1 is an elevation, part in perspective, of adevice constructed according to my invention. Fig. 2 is a detail view ofthe air-chamber and reservoir. Fig. 3*is a detail of the stopple. Fig. 4is a detail view of the nozzle-bulb. Figs. 5 and 6 are detail views,respectively, of the lower and upper valves of the atomizer-bulb.

The base A is provided in its upper side with a socket or seat, in which'flts the lower portion or reservoir, 13, of the bottle or airchamber B.A stopple, C, is fitted to the mouth of the bottle, and is provided withtwo tubes, 0 0, both of which project slightly above the stopple, inorder to receive the flexible tubes presently described. One of thesetubes, 0, projects only a short distance into the bottle or air-chamber,while the other, 0 extends down into the reservoir B, as will beunderstood from Figs. 1 and 2. A flexible tube, D, has one end connectedto the upper end of tube 0 and is provided at its other end with theatomizer-bulb D. This bulb is provided with valves D D arranged atrespectively its outer and inner ends, and most clearly shown in Figs. 5and 6. Aflexible tube, E, is connected at one end with the tube 0, andis provided at its opposite or outer end with a bulb-nozzle, E, which isprovided in its outer end with a discharge-opening, FF. This bulb isuseful 011 using the device, inasmuch as it fits the nostrils, and willenable the application of the vapor in such manner that none of it willbe wasted, and the nostrils will be closed, so the beneficial action ofthe vapor will be increased.

In operation it will be understood the bottle is supplied with asufficient quantity of the medicament in a fluid form to fill thereservoir B. The portion of the bottle above said reservoir is utilizedas an air-chamber. As the atomizer-bulb is operated in the usual manner,the air in the chamber is forced out through the bulb-nozzle in the formof a vapor.

In order to properly support the described parts, I bend a rod so as toprovide the standards F and the cross-bar F, forming an arch, which issupported on the base A by securing the lower ends of the standards Fthereto, as shown. This arch is provided with two lateral studs, G G,projected preferably from the cross-bar F, and a sufficient distanceapart to permit the base of the atomizer-bulb to be insertedtherebetween. By this means a convenient support is provided for thesaid bulb, where it may be held while. not in use, or when in use whereso desired.

On the main arch F F, I mount a supplemental frame or arch, H, composedof standards H, cross-bar H having supports I I, similar to supports GGr, and the spring-frame J. The bulb-nozzle is held when notin use bysupports II, and its upper open end is closed by anon porous flexiblesheet, J, stretched over frame J, which latter is made with a spring ortension, so as to hold the covering-sheet tightly over thedischarge-opening of the bulb-nozzle and prevent the evaporation of themedicament when the device is not in use.

It is manifest that where so desired, instead of forming the connectionof the atomizer-bulb through the stopper, as before described, saidconnection might be formed with the reservoir through the bottom or sidethereof. For convenience,I prefer the construction and arrangement asshown and before described.

Having thus described my invention, what I claim, and desire to secureby Letters Pat- 611b, IS.'
